While I am a big fan of Skype, I hate downloading updates to Skype. They sneak in more crap with each new version. Who wants a Skype toolbar? Now with version 6.1 and 6.2 Skype automatically integrates itself with Outlook 2010 or 2013. Upon reopening Outlook, you have a presence indicator to the left of each email address (some people have this already with Microsoft Lync). It might be great for some people but the little grey boxes annoy me and it annoys me further that there isn’t a quick way to remove the integration from Outlook. (Please correct me if I am wrong).
My first attempt at removal after cruising through the Skype menus was to delete the newly added registry key at \HKEY_CURRENT_USERS\Software\IM Providers\DefaultIMApp (Skype sets the value to ‘Skype’ and also adds some sub keys). I restarted Outlook and it was gone. Woohoo – until I restarted Skype and Outlook. Skype decided to reinstall itself as the default IM app and insert the annoying grey boxes again.
